hello I need help solving those questions please thank you so much in advance!
" S An 8.14kg mass moving east at 15.4m/s on a frictionless horizontal surface collides with a 11.2kg mass that is initially at rest. After the collision, the 8.14kg mass moves south at 2.57m/s. What is the magnitude of the velocity of the 11.2kg mass after the collision? Submit Answer Tries 0/10 What is the angle relative to the east? Submit Answer Tries 0/10 What percentage of the initial kinetic energy is lost in the collision? Do not enter units. Submit Answer Tries 0/10 ,0 S A person is watering the lawn with a garden hose. What force is necessary to hold the nozzle stationary if the discharge rate is 0.535kg/s with a speed of 23.4m/s? Submit Answer Tries 0/10 h 5 Romeo (81.1kg) entertains Juliet (55.5kg) by playing his guitar from the rear of their boat at rest in still water, 2.64m away from Juliet who is in the front of the boat. After the serenade, Juliet carefully moves to the rear of the boat (away from shore) to plant a kiss on Romeo's cheek. How far does the 75.1kg boat move toward the shore it is facing? Submit Answer Tries 0/10 ,0 S (5) Two blocks of masses M and 5M are placed on a horizontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them, as seen in the figure below. A cord initially holding the blocks together is burned; after this the block of mass SM moves to the right (the positive direction) with a speed of v1=1.74 m/s. (5a) What is the velocity of the block of mass M? Submit Answer Tries 0/10 (5b) Calculate the original elastic energy in the spring ifM = 0.330 kgStep by Step Solution
